VAPOR-BURNER.

Specification of Letters Patent.

Patented Feb. 1'7, 1920.

Application filed June 14, 1919. Serial No. 304,316.

To all whom it may concern:

Be it known that I, \VILLIAM T. vVoon, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Vapor- Burners, of which the following is a specification.

This invention relates to vapor burners, and more especially to those having a movable flame deflector producing a mixing chamber above the retort; and the primary object of the same is to produce a burner of this type which may be placed within a stove so that the flame may be spread over a considerable area under the stove top and therefore utilized to the best advantage.

Another object is to make the deflector or spreader in the form of ring which is removable when its use is not desired or re placeable in case it becomes warped or broken.

Another object is to improve the form of the spray nozzle so as to reduce the likelihood that it will become clogged.

The preferred embodiment of the invention is set forth in the following specification and claims and in the drawings:

igure 1 is a perspective view and Fig. 2 a vertical sectional view of the entire device.

Fig. 3 is a perspective detail of the deflector or ring.

The base is made in the shape of a pan 1 having a boss 2 at its center containing a threaded socket for receiving a nipple or plug 3. Onto the latter is screwed a T-coupling 4 with whose shank is connected the feed pipe 5 through which liquid fuel is conducted to the burner. Into the upper end of the head of the'T-coupling is screwed a nipple 6 which in turn is connected by an appropriate coupling 7 with a boss 8 communicating with the bottom of the burner head or burner proper. However, the plumbing connections described may be varied considerably, as it is only desirable that the base shall be a pan in which a little of the liquid fuel shall be burned for preliminary heating, and the pan shall be large enough to support the burner head reliably. The feed pipe 5 may be of metal if the connection with a remote source of liquid fuel supply is to be permanent, although this also is not important.

The burner head includes a hollow retort 10 and an integral gas arm yet to be described, and the retort chamber constitutes the generator of gas which flows thence through the arm. The bottom 11 of the retort by preference slopes downward to the boss 8, so that when the latter is removed from the coupling 7 any particles which may have collected within the generator chamber can be dislodged. The top 12 of the retort is by preference arched slightly, and a post 13 integrally connects the top and bottom at about the point shown, for strengthening these parts to resist the excessive heat to which they are subjected. In fact there could be a plurality of posts if desired. The gas arm 14 rises from one side of the retort as seen in Fig. 2 and curves inwardly over the top 12 thereof, its extremity by preference being closed with a plug 15 which is screwed into the same or otherwise rendered removable so as to permit cleaning out the arm from time to time. Gas is jetted from this arm through a nozzle 16 which is a nipple of peculiar construction. That is to say, its bore and jet orifices are of a size and shape necessary to produce the proper jet and to direct the spray downward as yet to be described, its body may be screwed into and through the wall of the arm or otherwise rendered removable, and its inner end 18 is preferably made conical so that particles may not lodge thereon and clog the bore. By preference a plug 19 is screwed through the wall of the arm 14 directly opposite the nozzle, so that access -may be gained thereto if desired, and when this plug is used the nozzle need not necessarily be removable.

In connection with the retort and jet nozzle described, use is made of a flame deflector shaped with that end in view and disposed so that also to an extent it serves as a mixing chamber. The numeral 20 designates a ring split at one side as seen at 21 in Fig. 3, having feet 22 and 23 at opposite sides of its split or opening 21 and a third foot 24 at what might be called its front, and the lower edge of its wall between these several feet elevated above their lower ends to produce an opening beneath the ring as seen at 25. On the sides of the arm 14 near its back and just above the top 12 of the re tort are lugs 26, and on the sides of the arm near its front but at a somewhat higher point are cast other lugs 27. The lugs are thus arranged in two pairs, and between the members of each pair the edges 28 of the ring are adapted to be passed when this element is applied to the burner head, the lower end of its three feet finally resting on the top late 12 of the retort.

With the feed pipe 5 connected to a source of liquid fuel supply, and the parts connected as described and the whole disposed preferably within a stove, fuel is admitted and rises into the retort 10, a little priming fuel is poured into the pan and ignited, and its heat warms the fuel in the retort and expands it or perhaps vaporizes it; it rises within the arm 14. and flows out the nozzle 16, being thereby directed obliquely downward into the ring 20 and onto the top plate 12 of the retort. Here it is, of course,mixed with air, and the mixture is ignited. It burns with an intense heat so that the top of the retort 10 (and through the post 13 its bottom also) becomes hot and the elfective generation of gas therein follows. The ring obviously serves both as a mixing chamber and as a flame deflector or spreader, because the flames will issue through the opening 25 all around ring, and effectively heat the interior of the stove and a considerable area of the top plate larger than the burner itself.

When the device is to be cleaned, the head can be uncoupled at 7. from the supporting structure, and particles within the generating chamber will fall out of the boss 8. The ring can be removed by slipping its edges 28 upward from between the pairs of lugs. The plug 15 can be removed and a brush run through the arm 14:, and if repairs to the nozzle are necessary it can be reached by moving the plug 19, and of course the nozzle itself may be replaced whenever it becomes necessary.

Having thus described the invention, what is claimed as new is:

1. A burner comprising a pan-shaped base head screwed onto said plug,

having a central boss provided with a threaded socket, a plug screwed into the socket, a T-coupling having one end of its a horizontally arranged fuel feed pipe connected with the shank of said coupling, a burner head including a retort and a gas arm, the head having a boss at its bottom, and detachable connections between said boss and the other end of the head of said T-coupling, said fuel pipe being arranged above said pan whereby the fuel is heated prior to entering the re tort.

2. In a burner, the combination with a retort, of agas arm rising from and overhanging said retort, a spreader ring arranged upon the retort in spaced relatlon to the same, and means to detachably secure said spreader ring in position, said gas arm having a discharge nozzle arranged at an angle to the upper surface of said retort whereby the flames are directed laterally from the retort through the space between the said spreader ring and said retort.

3. In a burner, the combination with a retort, a gas arm rising from one side of and curving over the same, and a nozzle directed downward onto the top of the retort, the arm having lugs on its opposite sides; of a split ring having feet to support it over the top of the retort, its sides adjacent its split detachably engaging said lugs.

41:. In a burner, the combination with a retort, of a gas arm rising from one side and curving over the retort and having a nozzle directed downwardly onto the top of the retort, said arm having pairs of lugs on opposite sides, and a ring of a size to overlie said retort beneath the nozzle, said ring being split and having its ends removably arranged between said pairs of lugs.

In testimony whereof I aflix my signature.

WILLIAM THOMAS WOOD. [L- 8.]
